Troubleshooting Internet at Home – How to Fix A Slow AT&T Internet Connection?


Having a dependable and quick internet connection is essential for daily activities, including streaming, online learning, remote work, and remaining connected with friends and family. If you have an AT&T internet connection at your home and you are experiencing really slow internet speeds, it can be frustrating for you and your family.

There are many troubleshooting steps you can take to diagnose and fix a slow AT&T internet connection before contacting customer service!

What to Do If Your AT&T Internet Is Slow?

To help you locate and fix the problem on your own, we will walk you through the entire troubleshooting procedure:

Check the Internet Speed

The first and most important step to take to troubleshoot your AT&T internet connection is to find out the actual speed of the connection that you are receiving.

To check your upload and download speeds, visit AT&T’s website and check the device speed with the help of its online speed test. You can also check the Wi-Fi gateway speed on its website.

But you need to consider variables like the time of day and network congestion that affect the speed and might cause it to fluctuate.

Compare the results to the internet plan and speed you have subscribed to. It’s important to dig deeper into the potential causes if the speeds are much slower than what you’re paying for.

Restart the Router

Temporary internet connectivity issues are frequently resolved by restarting your router. Simply unhook the power cables from the router, wait around 30 seconds, and then plug it back in to complete the task.

Give it a few minutes so that the router can reconnect and properly restart. Your network connection can be refreshed using this technique. Also, this technique can be used to resolve minor lags or glitches that you might experience while streaming a movie online or gaming.

Check for Interference

Your internet signal may be blocked or interfered with by several electrical equipment, including cordless phones, microwaves, and other Wi-Fi routers. This can be characterized by slower internet speeds and frequent glitches and lags.

So, you need to make sure that your router is positioned centrally and away from potential interference sources or signal blockages. The Wi-Fi signal may be obstructed by walls, big metal objects, and electronics.

Once you remove any form of interference or signal blockage, you will get faster internet speed, which makes for a lag-free online experience.

Update Router’s Firmware

Router companies frequently release firmware updates to either improve the performance of their routers, increase security, or fix any bugs.

To update your router’s firmware, you need to access the router’s settings through a web browser, find the “Firmware Update” option, and check if there are any available updates.
If there are any updates, follow the instructions to install the latest version of router firmware.

This not only enhances the router’s performance but also fixes any speed issues that you might be facing.

Check the Number of Connected Devices

Your internet connection may experience issues if several devices are connected simultaneously, slowing down the speed.

To fix this, you need to disconnect all the devices that are not in use. Alternatively, you can implement Quality of Service (QoS) settings on your router to prioritize certain devices or applications, including video conferencing or file-sharing applications.

Clear Browser Cache

The cache and cookies stored by your browser can increase over time and slow down your internet connection. Just like you do with Mediacom bundle deals, getting rid of these files will speed up your browser and sometimes even your internet connection.

To clear the browser cache and cookies, access your browser’s settings, locate the option to clear the cache and cookies, and then clear them. Additionally, to improve performance, consider updating your browser to the most recent version.

Get in Touch with AT&T Support

After trying all the troubleshooting steps and methods, if you are still unable to fix the slow internet connection; you need to get in touch with AT&T’s round-the-clock customer support.

Its technical support staff can run remote diagnostics to help you narrow down the problem. If they find out that it is a network infrastructure issue, they will send a technical team to fix the issue.

Meanwhile, you can utilize AT&T Wireless bundles to stay connected and online.


Although a slow AT&T internet connection can be frustrating and inconvenient, with the correct troubleshooting techniques, you can easily find and fix the problem on your own. You can see a noticeable boost in connection performance by testing your internet speed, resetting your router, and removing any interfering objects or blockages.

Keep in mind to routinely clear your cache and cookies, keep your device router’s firmware updated, and protect your network from potential dangers. Never hesitate to contact AT&T support for expert advice if everything else fails.
